Correct answer: D

To determine the sum of the first and second number, we can break the problem into clear, logical steps.

Step-by-Step Analysis
Find the Second Number:

The problem states the second number is 12% of 100.

Calculation: 0.12 × 100 = 12.

Find the First Number:

The problem states that two-thirds of the first number is equal to the cube of the second number.

First, find the cube of the second number (12): 12 × 12 × 12 = 1728.

Let the first number be x. The relationship is: (2/3)x = 1728.

To solve for x, multiply both sides by (3/2): x = 1728 × (3/2) = 864 × 3 = 2592.

Find the Sum:

Add the first number (2592) and the second number (12).

Sum = 2592 + 12 = 2604.

Correct Option
Option D: 2604
